Ok lets start:
1: First PS2 i was doing an infinity matrix mod, i power up nothing worked so yeah i took it out. Now the ps2 don't power up no more. i checked all the whole board and no splashes so i am stumped on that one.
2: Had infinity mod done to too! Everything worked ok. Took out the chip, now no video or audio. As usual no splashes and so.
3: Had a magic mod. Didn't work so took out. Boots up fine but next time i boot up. No video or audio.
